Walkie-talkies are hand-held, portable, two-way radio transceivers which enable secure communication between the two points, without being part of a network.
Answer:
- import random
-
- states = {
- "Alabama": "Montgomery",
- "California": "Sacramento",
- "Florida": "Tallahassee",
- "Hawaii": "Honolulu",
- "Indiana": "Indianapolis",
- "Michigan": "Lansing",
- "New York": "Albany",
- "Texas" : "Austin",
- "Utah" : "Salt Lake City",
- "Wisconsin": "Madison"
- }
-
- correct = 0
- wrong = 0
- round = 1
- while(round <= 5):
- current_state = random.choice(list(states))
- answer = input("What is the capital of " + current_state + ": ")
-
- if(answer == states[current_state]):
- correct += 1
- else:
- wrong += 1
-
- round += 1
-
- print("Correct answer: " + str(correct))
- print("Wrong answer: " + str(wrong))
Explanation:
The solution code is written in Python 3.
Line 3 -14
Create a dictionary of US States with capital as each of their corresponding value. Please note only ten sample states are chosen here.
Line 16 - 18
Create variables to track the number of correct and inaccurate response and also round counter.
Line 19 - 28
Set the while condition to enable user to play the quiz for five questions and use random.choice to randomly pick a state from the dictionary and prompt user to input the capital of selected stated.
If the answer matched with the capital value of the selected state, increment the correct counter by one. Otherwise the wrong counter will be incremented by one. Increment the round counter by one before proceed to next round.
Line 30 - 31
Print the number of correct responses and wrong responses.
Answer:
B. blocking I/O
Explanation:
Most of the input and output request placed to the computer considers the blocking request. It means that the controls given cannot be returned to the given application until and unless the input/output is complete.
Thus, blocking the input/output does not return till the input and output is complete.
With a blocking I/O, the process is moved to a wait queue when the I/O request is made, and it moved backs to the ready queue as soon as the request is complete, thereby allowing the other processes to run in the meantime.
Thus (B) blocking I/O is the answer.

This is called Real time processing. A Transaction Processing System (TPS) is a kind of data framework that gathers, stores, adjusts and recovers the information exchanges of an undertaking. Exchange handling frameworks additionally endeavor to give unsurprising reaction times to demands, despite the fact that this is not as basic with respect to continuous frameworks.
